Lecture Notes: many-body quantum dynamics with MCTDH-X
Paolo Molignini, Sunayana Dutta, Elke Fasshauer
The lecture notes on "Many-body Quantum Dynamics with MCTDH-X," adapted from the 2023 Heidelberg MCTDH Summer School, provide an in-depth exploration of the Multiconfigurational Ti…
Observables in non-Hermitian systems: A methodological comparison
Karin Sim, Nicolò Defenu, Paolo Molignini +1
Despite acute interest in the dynamics of non-Hermitian systems, there is a lack of consensus in the mathematical formulation of non-Hermitian quantum mechanics in the community. D…
Quantum Metric Unveils Defect Freezing in Non-Hermitian Systems
Karin Sim, Nicolò Defenu, Paolo Molignini +1
Non-Hermiticity in quantum Hamiltonians leads to nonunitary time evolution and possibly complex energy eigenvalues, which can lead to a rich phenomenology with no Hermitian counter…
